Abstract

A double circuit water tank of a pressure-bearing type solar heater is characterized in that a plurality of branch pipes which are arranged on a heating radiator in an inner container are extended out of the water tank. When the water tank is combined with a glass flat collector which is used in poor water quality areas for long time, the phenomenon of plugging can not occur in the flow passage of the glass flat collector, since water in the collector flow passage and water tank is respectively located in two circuits. If a vacuum tube collector is adopted, a solar vacuum thermal-collecting tube can be directly inserted on the branch pipe of the radiator, thereby limiting the temperature in the inner container, solving the problem of over-high water temperature of the vacuum pressure-bearing solar heater, since the radiator is closed to communicate with atmosphere, and uses water as medium.

Description

A kind of solar water heater's water tank

Affiliated technical field

The utility model relates to pressure-bearing type solar water heater's heat storage water tank.

Background technology

Vacuum tube pressure-bearing type solar water heater exists the overheated problem of water temperature, because the empty temperature higher (usually greater than 200 degrees centigrade) of shining of vacuum tube collector, at fine day, user's hot water use amount more after a little while, along with the stack of heat and the surge of hydraulic pressure day by day, water temperature can will jeopardize the service life of water heater and pipeline device up to more than 160 degrees centigrade.The glass plate heat collector replaces vacuum tube can prevent that water temperature is too high, still, if the glass plate heat collector is equipped with general bearing type water tank, is having freezing area usually to be damaged by frost, and its runner often gets clogged in the relatively poor area of water quality.In addition, vacuum tube collector in the winter time under the low temperature environment solar collecting performance preferable very with practical value, obviously hesitate to discard.

Summary of the invention

The utility model provides a kind of solar water heater's water tank, and purpose is that to solve vacuum tube pressure-bearing type solar water heater water temperature overheated and the glass plate heat collector is freeze proof and block problem such as runner.

The technical scheme that its technical problem that solves the utility model adopts is: the inner bag the inside at the pressure-bearing type attemperater has a radiator and this radiator to have a plurality of arms to stretch out outside the water tank.

Formed the double loop of heat exchange between the cavity of the inner bag of this water tank and the radiator.The arm of radiator connects the runner (perhaps connecting full-glass solar energy collecting vacuum tube) of glass plate heat collector, make the capacitation of solar thermal collector institute enter water tank through heat exchange, so whether block with various places water quality quality irrelevant in the runner of glass plate heat collector, walking the anti frozen liquid medium in its runner of freezing area is arranged can antifreeze (if vacuum tube, the heat collector runner can be opened wide and communicate, in order to clamp down on the water temperature in the water tank) with atmosphere.

The beneficial effects of the utility model are, if pressure-bearing type solar water heater glass plate heat collector, because the employing of anti frozen liquid heat transfer medium, the runner of glass plate heat collector can not be damaged by frost or block.If the employing vacuum tube collector, owing to open wide in its runner and communicate with atmosphere and be medium with water, radiator temperature in the inner bag can not exceed the boiling point of water, therefore pressure-bearing type inner bag interior heat coolant-temperature gage has just been clamped down on, and the overheated problem of vacuum tube pressure-bearing type solar water heater water temperature has obtained solution at this point.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 2 be radiator structure and with the inner bag assembled condition.

Fig. 3 is glass plate heat collector pressure-bearing type solar water heater.

Fig. 4 is all-glass vacuum tube pressure-bearing type solar water heater.

Among the figure, 1. pressure-bearing type inner bag; 2. shell; 3. radiator; 4. heat-insulation layer; 5. O-ring seal; 6. inner bag technology mouth; 7. ventilation liquid supplementation pipe; 8. water inlet water nozzle; 9. water outlet water nozzle; 10. collector; 11. arm; 12. bellows; 13. screw thread; 14. glass plate heat collector; 15. all-glass vacuum tube.

The specific embodiment

As Fig. 1, Fig. 2, pressure-bearing type inner bag (1) is left corresponding hole according to the arm number on the radiator (3), and the screw thread (13) of burn-oning outside each hole, in order to the arm (11) on (sealing) fixed heat sink (3).Radiator (3) adopts heat conductivility good metal tubing to make, go up according to the quantity of the vacuum tube quantity of the glass plate heat collector runner interface that connects of needs maybe at its collector (10), leave corresponding hole and the arm of burn-oning (11), arm (11) has one section bellows (12) with the collector connection place, in order to regulate the range deviation of correcting between each arm, when making radiator (3) with pressure-bearing type inner bag (1) assembling, after arm (11) passes screw thread on the inner bag, guarantee that each arm and screw thread are concentric, seal in order to screw thread.Ventilation liquid supplementation pipe (7) directly links to each other with the collector of radiator (3), and also there is screw thread (13) in its place of stretching out inner bag, and also there is bellows (12) itself and collector connection place, seal in order to screw thread.Inner bag technology mouth (6) is to establish for radiator (3) is installed, and radiator installs its shutoff soon.

Radiator (3) is if adopt the heatproof plastic products to reduce production costs, and this moment, collector can be made the flat box-like heat exchange area that helps enlarging.

As Fig. 3, the runner interface of glass plate heat collector links to each other with the radiator joint that stretches out water tank, from " ventilation liquid supplementation pipe (7) " perfusion heat transfer medium, the runner of glass plate heat collector and radiator is fused.Heat absorbing sheet on the flat plate collector obtains solar energy, because the principle of thermal siphon makes the interior heat transfer medium of radiator ceaselessly along direction of arrow Natural Circulation, radiator is advanced in the heat transmission, and heat exchange makes water tank produce hot water then.At no frost region, the medium in the runner can be a water, have frost region with anti frozen liquid for well.

The utility model becomes a kind of split type solar water heater's water tank simultaneously, its wall hanging is installed on the wall, by utilidor it is connected with user's the balcony or the solar thermal collector (glass plate or vacuum tube module) of windowsill outside, just become the natural recirculating type solar water heater; If solar thermal collector is installed on the roof or other is higher than the place of water tank, the small pump of can connecting in circulation pipe is to force the conveying solar energy.

As Fig. 4, the mouth of pipe of all-glass vacuum tube connects and is fixed on the radiator branch pipe connection that stretches out water tank through O-ring seal (5), from " ventilation liquid supplementation pipe (7) " perfusion water inlet, all-glass vacuum tube and radiator is fused.All-glass vacuum tube obtains solar energy, and the water generates convection current in the pipe is advanced radiator with the heat transmission, and heat exchange makes water tank produce hot water then.The freeze proof characteristic of all-glass vacuum tube is better, is that heat transfer medium has gone for frost region with water, at extremely frigid zones with anti frozen liquid for well.

When the utility model and heat pipe type vacuum pipe are formed the solar water heater, the condensation head of heat pipe type vacuum pipe can be inserted through O-ring seal and stretch out on the radiator branch pipe connection of water tank, from " ventilation liquid supplementation pipe (7) " perfusion water inlet, the condensation head of heat pipe type vacuum pipe just has been submerged when filling entire radiator, the heat that the condensation head transmits out enters radiator, and heat exchange makes water tank produce hot water then.
